York Trunk Sewer and Paisley-Clythe Feeder Main Project

The York trunk sewer Paisley-Clythe feeder main is a $30 million, multi-year infrastructure project. It is the City’s largest water main and wastewater (sanitary) sewer project. It includes the installation of about 6.2 kilometres of water pipes and 3.8 kilometres of sewer pipes. The City’s 2009 Water and Wastewater Servicing Master Plan identified the projects as priorities in order to meet our community’s existing and future water and wastewater servicing needs.

As part of the project planning, the City of Guelph completed a Municipal Class Environmental Assessment (EA) study in 2012 and the project proceeded to detailed design and construction.

York Trunk sanitary sewer

The York Trunk sanitary sewer is being upgraded. A sanitary sewer carries wastewater from homes and businesses to a wastewater treatment plant where it is treated before being discharged into a body of water.

Our city’s infrastructure needs to be replaced or repaired over time in order to ensure good working condition and to accommodate changes in demand. The existing York Trunk sanitary sewer is reaching the age where it is in need of replacement, and growth in our community means we also need a larger sewer pipe.

This sanitary sewer runs alongside the Eramosa and Speed Rivers from the former Guelph correctional centre lands to the Wastewater Treatment Plant on Wellington Street, just west of the Hanlon Expressway.

Paisley-Clythe drinking water feeder main

The Paisley-Clythe drinking water feeder main is new. A feeder main is a large pressurized pipe that carries—or feeds—water straight from one place to another. Unlike water mains, feeder mains do not connect to homes or businesses.

This new feeder main will improve the movement of water between the F.M. Woods Pumping Station and two reservoirs at the west (Paisley) and east (Clythe) ends of the City. Water from those reservoirs is supplied to homes and businesses by water mains.

Project schedule

This project is divided into three phases. Phase 1 began in 2014, and completion of Phase 3 is expected by 2018.

Phase 1

Phase 1 of the project includes the installation of about 2,200 metres of water and sewer pipes. With a construction budget of $9.9 million, this phase includes the area from Silvercreek Park eastward to York Road Part at the covered bridge. Phase 1 will be completed in 2016.

Phase 2

Phase 2 will be completed in two stages. The first stage includes the installation of water and sewer pipes from York Road Park at the covered bridge eastward through York Road and Eramosa River Parks to the F.M. Woods Pumping station on Waterworks Place. This phase of the project begins in spring 2016 and includes the installation of about 1.500 kilometres of water pipes and 1.5 kilometres of sewer pipes.

The second stage include the installation of water pipes from the F.M. Woods pumping station up to York Road, and the installation of sewer pipes from the F.M Woods pumping station to Victoria Road. This work is expected to begin in 2017 or 2018.

Phase 3

Phase 3 of the project includes the remaining section of water pipe from York Road to the Clythe pumping station and reservoir at the east end of the city. The timing for this section of this phase is yet to be determined.

The Paisley pumping station and reservoir section at the west end of this phase is in design with construction expected to start in 2017.
